A recent study from Denmark suggests that eating foods high in potassium, such as bananas, avocado, and spinach, can lower the risk of heart disease, hospitalization, and death by nearly a quarter. The research involved heart patients with implanted defibrillators, some of whom received guidance to increase their intake of potassium-rich foods. Those who followed the dietary advice experienced a notable reduction in health complications compared to those who did not change their diet. The findings highlight the importance of potassium for heart health and suggest that modern diets, which often lack sufficient potassium, may contribute to increased risks.
